Industrial hygiene specialists from the National Institute for Occupational Safety and Health (NIOSH) visited hospitals and medical centers throughout Taiwan. They assisted with designing and evaluating ventilation modifications for infection control, developed guidelines for converting hospital rooms into SARS patient isolation rooms, prepared designs for the rapid conversion of a vacated mili...

Overheating in buildings not only causes discomfort to the occupiers but – if it occurs regularly or over a sustained period – also leads to pressure for the installation of mechanical cooling. In addition to the initial cost and ongoing maintenance requirements of such systems there will be an increase in the overall energy use of the building. This paper investigates the thermal performance o...

For several years ST/CV at CERN has amassed considerable experience in designing and operating cooling and ventilation plants for the particle beam accelerators and physics experiments. To achieve optimal plant operating conditions a complete study of the control objectives is required. This implies to define carefully the control architecture at the beginning of the process control design stag...

ventilation tube (vt) insertion is the most common otologic operations performed in children, which has great importance in recovery and prevention of hearing loss in children with eustachian tube dysfunction in critical ages of growth development. the location of the vt insertion varies in different studies; the differences are in recovery rates and sequelae of vt insertion. this study is perf...

conclusions pressure support ventilation, but not spontaneous breathing, induces a significant redistribution of ventilation towards the ventral region. the sensitivity of the support trigger appears to influence the distribution of ventilation only during the early phase of inspiration. background in supine position, pressure support ventilation causes a redistribution of ventilation towards t...

Industrial power plant buildings differ from all other types of buildings, mainly due to their significant heights and volumes without internal floor sections, exceptionally heat gains during daily work, potentially high fire risk. Those consist boiler turbine houses with multilevel stairways. This complicated architecture creates an extraordinary natural thermal stack effect, causing special v...

Most cities in China, especially industrial cities, are facing severe air pollution, which affects the health of residents and development cities. One most effective ways to alleviate pollution is improve urban ventilation environment; however, few studies have focused on relationship between them. The Frontal Area Index (FAI) can reflect obstructive effect buildings wind. It influenced by arch...
